Description:
        Bash 3 breaks array expansion

Repeat-By:
        #!/bin/bash
        x=(one two)
        echo address@hidden:1}
        # prints nothing in bash 3
        # prints two in bash 2

        x=(one two three)
        echo address@hidden:1}
        # prints two three as expected in bash 2

Fix:
        (really a work around)
        #!/bin/bash
        x=(one two)
        x=("address@hidden" "xxx")
        echo address@hidden:1:address@hidden - 2}
